| Abstract: | 46
resistant or susceptible soybean entries screened from 6724 accessions together with 5
released cultivars were evaluated for their resistance to cotton worm (Prodenia litura
(Fabricius)) in net room according to their defoliation percentage during 1997～1998． The results showed that there existed significant
difference in the resistance of soybeans to cotton worm among varieties, record dates and years, and there also existed
significant interactions between varieties and record dates, and between varieties and years． A set of accessions performed consistently better than the
commonly used resistance sources, PI227687, PI171451 and PI229358, were screened out for breeding purposes．Tab 3, Ref 10 |
